Thermal Settings, Unhide or Bios-Mod ?

[Ricardo Bernal]

Dear members, greetings from Brazil,
I come here to get any help with my problem, I have a notebook remarked as Intelbras i211
I just did an upgrade of processor from celeron to core 2 duo T5550 and it works very fine and fast, but, the thermal sensor it´s crazy and shut dowm my system when processor is working at 100% more than 1 - 2 minutes making cpu stress with the Everest software. The report says 115º C but I think it´s wrong, just put my finger at top heatsink processor and its very ..very cold, so, maybe any hide settings at Bios do my system shutdown.
Well, I need any help to fix this problem, any suggestion ?
